Light Stabilizer 770
Appearance is white crystalline powder.
Melting point 81℃～86℃, soluble in ethanol, ethyl acetate, benzene and other organic solvents, insoluble in water.
It is a representative variety of low molecular weight HALS. Its light stabilization efficiency is high, suitable for polyethylene, polypropylene chemical bookene, polystyrene, ABS and other products, especially in polyolefin products, the light stabilization effect is 3 to 4 times that of ultraviolet absorbers and nickel quenchers. The molecular weight is small, the volatility is large, and the resistance to migration and extraction is poor, so it should be used in thick products.
